Filed: 1986-02-20
Abstract: PURPOSE:To remarkedly improve the attractive force of the electrostatic attraction mechanism for the titled mechanism, to increase a cooling gas pressure and to improve the cooling efficiency of the gas by providing protrusions on the central part region only of the circular end surface of the electrostatic attraction mechanism. CONSTITUTION:Protrusions 16 are formed on the central part region 19 only of the circular end surface of an electrostatic attraction mechanism 6.

Title: Address converting system of channel memory in time division exchange system
Inventor: ABE MASATOSHI
IPC: H04Q11/04
Filed: 1982-03-09
Abstract: PURPOSE:To secure the normal connection in case a fault arises to a part of the data area of a channel memory, by using a spare area to change the address of a faulty area given from a control memory to the address of the spare area. CONSTITUTION:A channel memory SPM-P receives the writing and reading addresses from a counter CNT and a control memory CM via selectors SEL1 and SEL2 respectively when no fault arises. Then the memory SPM-P performs an exchange connection between incoming and outgoing highways FHWM and  BHWM after the sequential writing and random reading of the writing and reading addresses. If a fault arises within the memory SPM-P, the address of the  SPM-P and the address of a spare area SRM-S to be switched are set to buffers BURO and BUR1 respectively by a control part CPU. When the address delivered from the selector SEL2 is csoincident with the fault address within the buffer BURO, a comparator COMP switches the selector SEL1. Then the address of the area SRM-S within the BUR1 is given to the memory SPM-P in  place of the fault address.

In a playback process, a relative position between a continuous unloader and a ship 7 is computed on present signals supplied from automatic tracking type sensors 9, 9. Next, whether the relative position and the stored operational information of the ship 7 coincide mutually or not is judged. In the case where the relative position and the operational information are different, a running section 1 and a boom 2 are driven, and the absolute position of the unloader is therefore corrected by the control device so that a difference between the relative position and the operational information may be zero.

Title: Semiconductor laser
Inventor: HAYAKAWA TOSHIROU
IPC: H01S5/323
Filed: 1979-03-27
Abstract: PURPOSE:To increase the operating life of a semiconductor laser by suitably selecting an aluminum mixture crystal ratio of a clad layer made of Ga1-xAlxAs interposed between active layers through a double hetero junction for the aluminum mixture crystal ratio y of an active layer made of Ga1-yAlyAs. CONSTITUTION:The carrier recombination by the energization of a double hetero junction semiconductor laser is enhanced in the migration of defect to the vicinity of the junction to accelerate its deterioration. If the clad layer is further of indirect transition type, the electron recombination disposed at the conduction band bottom except a point gamma contributes to increase in the junction boundary surfaces and to induce the lattice vibration. Therefore, the defect is migrated vigorously as compared with the direct transition. The mixture crystal ratio y of the active layer is set at y>=0.10 corresponding to the oscillating wavelength of the visible light range, to effectively enclose the carrier and the light the mixture crystal ratio of the clad layer is controlled with the conditions of x-y>=0.2, and to set the clad layer at direct transition type, the limiting condition of x>=0.45 is set. Thus, the operating life of the laser can be increased.
